Collapsible Lockable Support Frame Assembly for Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display device support frames fail to maintain balance and prevent accidental movement or collision when transitioning from vertical to horizontal positions, leading to potential damage during delivery and storage.
Innovation Solution
A collapsible lockable support frame assembly with an upper stop member to prevent outward displacement and a lower stop member to limit inward displacement, utilizing pivotally connected stop members that engage due to gravity to lock the display device in place when rotated from vertical to horizontal positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the support frame is turned from vertical to horizontal position for packing and delivery, then the packing size is reduced and transportation cost is saved, but the display device cannot be kept in balance and may move accidentally causing damage
Solution Approach 1:
The locking mechanism is activated before delivery to preemptively secure the display device in the horizontal position. The upper stop member engages with the locking protrusion on the slide holder, and the lower stop member limits inward displacement, preventing any accidental movement during transport.
Solution Approach 2:
The upper stop member and lower stop member act as intermediary elements between the display device and the support frame. These components mediate the interaction by providing mechanical constraints that maintain balance and prevent movement when the frame is in horizontal position.
2Volume of moving object
If the display device is pushed inwards to minimize space occupation after moving to horizontal position, then space occupation is reduced, but the display device may hit the support arm of the base
Solution Approach 1:
The lower stop member serves as an intermediary component that mediates between the slide holder and the support arm. It provides a controlled stopping point that allows inward displacement for space minimization while preventing excessive movement that would cause collision with the support arm.
Solution Approach 2:
The lower stop member is positioned in advance to establish a predetermined limit for inward displacement. This preliminary positioning ensures that when the display device is pushed inwards, it automatically stops at a safe distance from the support arm, preventing collision damage.
3Ease of operation
If a constant force spring is provided to impart upward force to the slide holder, then the display panel can be positioned in adjusted position, but the weight of the display device cannot be kept in balance with the spring force when in horizontal position
Solution Approach 1:
The system transitions from a static spring-force balance to a dynamic locking mechanism. When in vertical position, the constant force spring provides continuous upward force for position adjustment. When rotated to horizontal position, the upper and lower stop members engage to provide dynamic mechanical constraints that maintain balance without relying on spring force equilibrium.

Function Achieved in This Case
Ensures secure locking and balanced positioning of the display device in both vertical and horizontal orientations, preventing accidental movement and collision with the stand, thus enhancing safety and usability during transport and storage.
Implementation Method 1
the upper stop member and the lower stop member are forced by the gravity thereof to turn out swingingly of the casing so that the upper stop member stops the positioning member from outward displacement to lock the slide holder

AI summary
A collapsible lockable support frame assembly includes a support frame pivoted to the support arm of a stand and having two parallel sliding rails, a slide holder carrying a positioning member at the back side and coupled to and movable along the sliding rails of the support frame for holding a display device and a locking mechanism having a casing affixed to the support frame and an upper stop member and a lower stop member pivotally swingingly connected to the casing. When the support frame is turned from a vertical position to a horizontal position, the upper stop member and the lower stop member are forced by the gravity thereof to turn out of the casing so that the upper stop member stops the positioning member from outward displacement to lock the slide holder, facilitating packing and delivery and the lower stop member limits the inward displacement distance of the slide holder to prohibit the display device from hitting the support arm of the stand.
